The interior of the first half tube 152 is provided with a first half ring 162, and the interior of the second half tube 154 is provided with a second half ring 164. The first half tube 152 is combined face-to-face with the second half tube 154 to constitute the connecting pipe 15; whereas, the first half ring 162 is combined face-to-face with the second half ring 164 to constitute the stop part 16. The bottom rim in the main unit 1 is protruded with an arc-shaped standing wall 17 which is disposed on the top rim of the bottom seat 12. As shown in FIG. 4, if the radius of the inner surface 172 on the arc of the standing wall 17 is R, and the shortest distance between two terminal ends on the arc of the standing wall 17 is L, then L is smaller than 2R. In addition, the two terminal ends 172 on the arc of the standing wall 17 are disposed between the arc center of the standing wall 17 and the second half tube 154.

Referring to FIGS. 1 to 3 again, the press element 3 is a tube object with a closed end, and is loosely disposed in the through-hole 13 of the main unit 1. The outer radius of the press element 3 is a little smaller than the inner radius of the through-hole 13 and an end of the press element 3 is formed with a top plate 31 outside the main unit 1. The top plate 31 seals an end of the press element 3 and is used to sustain with the applied force exerted by a user. The other end of the press element 3 is extended in the through-hole 13 to form an orifice end 32. The interior of the press element 3 is provided with a first tube column 33 along the center axis of the press element 3, one end of the first tube column 33 is connected with the top plate 31, and the other end of the first tube column 33 is extended toward the main unit 1.

The suppression disk 5 is disposed in the main unit 1, the outer radius of the suppression disk 5 is larger than the inner radius of the through-hole 13, and the rim of the suppression disk 5 is in adjacent to the restraint part 14, allowing the restraint part 14 to restrict the suppression disk 5 along one direction. The suppression disk 5 is connected with the orifice end 32 of the press element 3, the top rim of the suppression disk 5 is protruded with a loop 51 and a second tube column 52, and the second tube column 52 is formed at the center of the loop 51. The bottom rim of the suppression disk 5 is concaved with a circular trough 53, and the loop 51 passes through the orifice end 32 and is extended into the press element 3. The outer circumference of the loop 51 is in adjacent to the inner wall of the press element 3, so as to provide the convenience in positioning the suppression disk 5 relative to the press element 3. The terminal end of the second tube column 52 is in adjacent to the terminal end of the first tube column 33, and the suppression disk 5 is connected with the press element 3 by a bolt 54 which penetrates the second tube column 52 axially and is screwed with the first tube column 33.

The air cylinder 6 is disposed in the main unit 1 and is a circular cylinder made of an elastically deformable material. The top end of the air cylinder 6 is formed with a flat pressure bearing plate 62, the bottom end of the air cylinder 6 is formed with a bottom plate 64, and a central tube 66 is formed between the pressure bearing plate 62 and the bottom plate 64. The pressure bearing plate 62 is in adjacent to the bottom rim of the suppression disk 5 and is extended to the trough 53, allowing the top end of the air cylinder 6 not to slide laterally by restricting and positioning the top end of the air cylinder 6 by the annular periphery of the trough 53. The bottom plate 64 is in adjacent to the top rim of the bottom seat 12 and is disposed on the inner side on the arc of the standing wall 17 which restricts and positions the bottom end of the air cylinder 6, allowing the bottom end of the air cylinder 6 not to slide laterally. The central tube 66 is corrugated along the direction pointing to the pressure bearing plate 62 and the bottom plate 64, so that the air cylinder 6 can be extended or shortened elastically and repeatedly along the central axis, thereby attracting or squeezing air to enter or exit the air cylinder 6.

The nozzle 7 is a tube object disposed in the connecting pipe 15, and an end of the nozzle 7 is connected with the bottom at the side rim of the air cylinder 6. The nozzle 7 is connected with the interior part of the air cylinder 6, allowing air to pass through the nozzle 7 to enter or exit the air cylinder 6. The other end of the nozzle 7 is extended into the loop space of the stop part 16, and a terminal end is formed with a guide part 72 in the cone shape. The guide part 72 is used to guide the bullet to sheath with the nozzle 7.

As shown in FIG. 1, FIG. 5 and FIG. 6, two sides of the main unit 1 are formed respectively with a hanging rod 18. The tie band 8 is a soft and bendable band, the middle section of the tie band 8 is disposed at the bottom rim of the main unit 1, and the tie band 8 wraps around each hanging rod 18. In addition, two ends of the tie band 8 are loosely joined by a joint structure (not shown in the drawings), so that two ends of the tie band 8 can be joined together or separated from each other. The joint structure is a Velcro tape which can be optionally replaced by a fastener constituted by the male retainer and the fitted female retainer. The tie band 8 is an optional assembly and is used to position the main unit 1 on a palm or other part of the user. If there is no tie band 8, the user can hold the main unit 1 with a hand to operate the cracker snap that sprays the projectile.

Upon using the abovementioned embodiment, the main unit 1 can be emplaced at the user's hand, with the bottom seat 12 being in adjacent to the center of the palm. Next, two ends of the tie band 8 are joined together at the back of the hand by the joint structure. Therefore, the embodiment can be positioned at the user's hand. In using the embodiment, the tie band 8 can be optionally emplaced at the back of the user's hand.

As shown in FIG. 7, when the bullet 9 is put in the abovementioned embodiment, the rear end of the bullet 9 is inserted into the connecting pipe 15.

The bullet 9 includes primarily a shell 91 in the shape of a round tube, a front sealing plate 92, a rear sealing plate 93 and plural projectile 94. The rear end in the shell 91 is formed with a sleeve 95, and the inner radius of the sleeve 95 fits with the outer radius of the nozzle 7, so that the sleeve 95 can be axially sheathed with the nozzle 7. Inside the shell 91, a chamber 96 is formed at the front end of the sleeve 95, the rear end of the chamber 96 is connected with the sleeve 95, and the front end of the chamber 96 is connected to ambient at the front end of the shell 91. The front sealing plate 92 and the rear sealing plate 93 are disposed in the chamber 96 radially, and the outer peripheries of the front sealing plate 92 and the rear sealing plate 93 are in adjacent to the peripheral wall of the chamber 96. The front sealing plate 92 is in adjacent to the front end of the chamber 96, and the rear sealing plate 93 is in adjacent to the sleeve 95; whereas, the projectile 94 are loaded in the chamber 96 and disposed between the front sealing plate 92 and the rear sealing plate 93.

When the bullet 9 is inserted into the connecting pipe 15, the rear end of the bullet 9 is abutted at the stop part 16, and the sleeve 95 is sheathed at the front end of the nozzle 7. At this time, if the axis of the sleeve 95 is not disposed on the extension line of the axis of the nozzle 7, then the sleeve 95 can be still easily sheathed at the front end of the nozzle 7 by the cone-shaped guide part 72. Moreover, by forming stop to the bullet 9 by the stop part 16, the bullet 9 can be prevented from entering the sleeve 15 too deep. In addition, a tiny gap can be formed between the front end of the nozzle 7 and the rear sealing plate 93, avoiding the nozzle 7 to contact with the rear sealing plate 93.

As shown in FIG. 8, after the rear end of the bullet 9 has been inserted into the connecting pipe 15, the press element 3 is tapped to pull the suppression disk 5 to press the air cylinder 6. The air cylinder 6 is squeezed by the suppression disk 5 and the bottom seat 12, allowing the central tube 66 to be deformed elastically along the axis. Air in the air cylinder 6 will then pass through the nozzle 7 and be sprayed into the bullet 9, which increases the air pressure between the rear sealing plate 96 and the front end of the nozzle 7 in the bullet 9. The air pressure will act onto the rear sealing plate 93 to form a push force, enabling the front sealing plate 92, the projectile 94 and the rear sealing plate 93 to displace toward the front end of the bullet 9, exit the shell 91 and fly outward, thereby accomplishing one time of operation for spraying the projectile 94.

After the front sealing plate 92, the projectile 94 and the rear sealing plate 93 have flown out of the shell 91, the internal spaces of the chamber 96, the sleeve 95, the nozzle 7 and the air cylinder 6 are connected together, and there is no need to withdraw the shell 91 out of the connecting pipe 15 to release the pressing to the press element 3. The central tube 66 will restore to its initial state due to the elasticity and attract ambient air to pass through the chamber 96, the sleeve 95 and the nozzle 7 from the front end of the shell 91 to flow into the air cylinder 6. In addition, the pressure bearing plate 62 will push the suppression disk 5 and the press element 3 to restore to their original positions. Next, the user withdraws the shell 91 from the connecting pipe 15, and loads another bullet 9, which has not yet sprayed the projectile 94, into the connecting pipe 15 to perform another operation for spraying the projectile 94.

The air cylinder 6 is disposed in the main unit 1 and the press element 3 pulls the suppression disk 5 to press the air cylinder 6. The applied force with which the suppression disk 5 presses and deforms the air cylinder 6 is distributed to the flat pressure bearing plate 62, increasing the reliability in squeezing and deforming the air cylinder 6 to push air into the bullet 9 to spray the projectile 94. Besides that, the main unit 1 forms isolation and protection to the air cylinder 6, which prevents external foreign objects from puncturing the air cylinder 6 to affect the efficiency of squeezing and attracting air through the nozzle 7 by the air cylinder 6.

The user can hold the main unit 1 with one hand and uses the other hand to install the bullet 9, tap the press element 3 to spray the projectile 94 and remove the bullet 9. The user can also clap hands with other person, letting other person to tap the press element 3 to accomplish the operation for spraying the projectile 94. If the main unit 1 is chosen to be disposed on an arm, then the user can tap the press element 3 by oneself or other person can tap the press element 3 to finish the operation for spraying the projectile 94, which provides a variety of ways of playing for fun.
